A box slides from rest from a point A down a plane inclined 30° to the horizontal. After reaching the bottom of the plane, the box move at horizontal floor at distance 2m before coming to rest. If the coefficient of friction between the box and the plane and the box and the floor is 0.40, what is the distance of point “A” from the intersection of the plane and the floor?

A force of 100 N is applied on a crate to push it over 10 m factory floor horizontally and the friction force offered by the contact surface is 70 N then calculate the kinetic energy gained by the crate.

What will be the force of static friction on a crate lying on a horizontal ramp?

Consider a problem in which a car of the mass ‘m’ is moving on a road tilted at an angle from the horizontal. What will be the normal reaction of the surface?
